Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
I'm thinking it may not be too easy to haul the throttle body off, but I'd
imagine that would make it much easier to clean properly?

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
BTW, this problem SEEMS to have started about the same time as I hauled the
old radiator and water pump out and replaced it. Could very easily just be
coincidence, though. I've tried checking all the vacuum hoses in particular
around the area I was working in, but nothing popped up.
I'm tempted to head out to a wrecker, and see about snagging an old throttle
body (preferably with sensors), just for S&G. Give me something to swap out
some parts to try seeing what's wrong.
So it's not seeming that bad CCV valves/hoses should be causing the high
idle, though?

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
It's only four bolts that hold the TB on, and the cables. Takes about 5
minutes to pull. Don't loose the cable clips, and be sure you make a note of
what cables go where.

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
It's only four bolts that hold the TB on, and the cables. Takes about 5
minutes to pull. Don't loose the cable clips, and be sure you make a note of
what cables go where.

Re: Still having high idle problem on 88 Jeep Comanche (4.0l)
That's the thinking. The theory is that your IAC has carbon in it, which is
making it function improperly, which is what is messing with your idle
speed. Cleaning the contacts for the various sensors mentioned can help
too.
